I have the Note 2 SGH-I317M Canada (firmware from Rogers) but that firmware doesn't include Spanish language. Can I flash the phone with a firmware for Note 2 SGH-I317 from AT&T so I can use spanish language? My phone would brick if I install the AT&T firmware? Please answer me. I have another problem. Anybody can't hear me when they call me through whatsapp, messenger or any other app, unless I a active the speaker. They only hear me when I call through my sim card network.
